ROTHBURY, MI -- Thursday was a day of traffic backups in the area of the Electric Forest music festival in Rothbury, but police expect Friday to be easier.

"I think the majority of people are already arrived," Michigan State Police Sgt. Charles Hockanson said around 9:30 a.m. Friday. "It’s going to be noticeable, it's going to be steady, but it’s probably not going to be quite the influx that we had yesterday."

Thursday was a different story. "There were some backups yesterday," said Hockanson of the state police Hart post. "That's typical when you're trying to shove tens of thousands of people into one place."

Organizers said about 15,000 people were expected to attend the festival.

Traffic on U.S. 31 heading to the Rothbury area was flowing smoothly all
day Thursday, MLive reporter Andrew Dooley reported, but it backed up significantly around the festival grounds on
80th Avenue and Cleveland Road all day.
